<p>Method and device for separating the legs from a body part of slaughtered poultry. The method comprises the following processing steps: positioning the carcass part (1), formed by the body part and the legs, on the rear side, with the legs pointing upwards, relative to cutters (28, 38, 40); making a groin incision between each leg and the body part at the side of the leg facing the body part; dislocating each leg in the hip joint by bending or pressing out each leg relative to the body part; making a back incision between each leg and the body part, on the rear side of the body part, in the lengthwise direction of the backbone; pulling the legs off the body part, essentially in the lengthwise direction of the backbone and in the direction away from the tail part; and after dislocating of the hip, making a caudal hip incision in the remaining tissue connection between each leg and the body part. The two parts of each dislocated hip joint are moved a certain distance apart prior to making the hip incision. The device comprises a conveyor (2) for bringing in carcass parts (1) hanging by the legs, a guide channel disposed below the conveyor (2) and running parallel thereto for the rear side of the body part, which guide channel merges in the direction of conveyance into a guide face above which at a certain distance a conveyor chain (30) can move in the direction of conveyance (4) past the end of the conveyance by the conveyor (2), groin cutters (28) which are fitted on either side of the vertical plane of symmetry of the conveyor chain (30), leg push-out strips (8) which are fitted on either side of the above-mentioned plane of symmetry, downward running leg guides (8) diverging laterally in the direction of conveyance, behind which guides hip cutters (38) and back cutters (40) are provided on either side of the guide face, and a plate chain (50, 52) which can move below the guide face in the direction of conveyance (4) at a higher speed than the conveyor chain (42) moved along above it, the plates of the plate chain being provided with V-shaped recesses (56) at the side lying in the direction of conveyance. The leg guides comprise joint ball guides (36) which can push the joint ball of each dislocated hip joint over a certain distance away from the hip joint socket prior to the making of the hip incision. <IMAGE></p> |
